Question / Help Game audio lagging behind gameplay video with Dazzle

[Horsedad]

About a month ago, I switched to OBS because it makes the video quality of my stream look much better. However, I noticed that the game audio is around a 1/2 second (maybe more) behind the actions on screen (i.e. mario jumps and the jump sound isn't heard until about a 1/2 second after the jump). I've tried for hours messing with delay, watching online tutorials, reading forums, etc., but I can't find a solution. The capture device I'm using is a dazzle and i'm capturing my NES. I've attempted to post a log file, but I'm not confident it actually uploaded after many attempts, so let me know if that is still needed.

Some additional info:

1. I guess I didn't realize the log would be from the entirety of the time I had OBS open. The stream with the settings I would usually use (that have the audio lag issue) would be found toward the end of the log (sorry about that).
2. Here's a link to the stream shown at the end of the log, in case you want to see it in action: https://www.twitch.tv/horsedad/v/82450848
3. If you watch the stream, I had the sound turned on the Twitch dashboard the first 2 minutes to try and listen for the delay, so you'll probably want to skip to about 2 minutes into the video to hear it as it normally would be presented.
4. I notice my stream audio picks up the ad that Twitch plays when you begin streaming, which can be heard at the beginning of the video I linked. Wanted to mention in case that has any implication as to a settings error I have going on.

I probably won't be able to reply over the next 4 days, as I'll be on vacation, but I was hoping to have some potential solutions to try so I can speedrun when I get back. When I return, I will be actively replying to anyone's potential fixes. Thanks for trying to help.

Also, just found this during the last stream in the log:

11:16:05: Audio timestamp for device 'Dazzle Video Capture USB Video Device' was behind target timestamp by 300
